How Much Sleep Do You Actually Need by Age?
Sleep requirements aren’t one-size-fits-all, and they change significantly from infancy through older adulthood—yet many people still judge their rest by a single “eight hours” rule. This guide outlines age-based sleep recommendations from newborns to seniors, explains why those targets shift over time, and shows how too little or poor-quality sleep can affect mood, focus, immunity, and long-term health. It also highlights common misconceptions about catching up on weekends or relying on naps, and shares practical, actionable steps to improve your sleep routine and wake up with more consistent energy.
